Confirmed Torsen Differential
I'm happy about this!
"Good news! Toyota 86 will feature Torsen LSD and gearbox is from Toyota Altezza / Lexus IS (automatic from IS-F), so we already have tons of spare parts. Almost all suspension is the same as Impreza" |

the automatic in the IS-F has eight gears
http://en.wikipedia.org/wiki/Lexus_IS_(XE20)#IS_F_SPDS I´m pretty sure they mean IS 250 or IS 350 |

I want to know if they are using the Subaru r160/r180 diffs. If so, then we will have plenty of aftermarket support out of the box.

Manual one is based off IS300's tranny, but I think the one in FR-S/BRZ is upgraded version.

Cool.
If it's an existing diff that gives more opportunity for aftermarket options like OS Giken, Quaife, or whatever you prefer.

I seem to recall it being mentioned to be Toyota piece, but I could be wrong. It wouldn't be an R160 or R180 though, those are much too weak for a RWD car. They are Nissan diffs, and the last time either of them was used in a rwd production car was the 510 and the original 240z respectively. If they were going to use a Nissan diff, the obvious choice would be the R200 (silvia/240sx, n/a 300z) as it is quite strong, and is an easy transplant into the Impreza rear subframe.

I don't really care if it's a Subaru piece, I'm just looking for reliability and aftermarket compatibility. |

I've been doing a bit of reading.
The pumpkin is from the IS, but the differential itself is very likely to be the same one that comes in the IS-F. The IS-250/350 have open diffs as far as I can tell, while the ISF comes with a torsen. Aftermarket-wise, there are currently replacements available from OS Giken and Tom's. And if the ring/pinion gears are as strong as those in the IS's, there shouldn't be any need to worry about it's strength. |

My first post here I actually just joined to ask what kind of diff this car will have - really good news about the Torsen! I assume this will be the same for both variants (BRZ and GT-86)?
I currently drive a BMW 1-series coupe (120d), and fitting a Quaife diff in it last year completely transformed the car! Made this vid right after the run-in period was over, hopefully the GT-86 will be at least as happy to powerslide [U2b]fLFupcWTdAs[/U2b]
